“…The oil sardine along the coast of Oman has also shown interannual changes and has exhibited a declining trend from 2001 to 2011. The major reasons cited are rising sea temperature, thermal stratification of the water column and the trophic pressure imposed on sardine populations by large pelagic predators (Piontkovski et al, 2011).…”

“…Increase in SST influence the marine biological systems at organismal, population, community and ecosystem levels (Vivekanandan, 2013). The chlorophyll abundance is a vulnerable factor to oil sardine fishery as it determines the feeding ground and controls its recruitment (Piontkovski, Al-Oufi, and Al-Jufaili, 2014;Zaki et al, 2012). With the advent of satellite remote sensing techniques (George, 2014), satellite aided information of chlorophyll abundance were utilized for unravelling the fluctuation in the abundance of IOS fishery (George et al, 2012;Menon et al, 2019).…”

Sajna, V.H.; Zacharia P.U.; Liya, V.B.; Rojith, G.; Somy, K.; Joseph, D., and Grinson, G., 2019. Effect of climatic variability on the fishery of Indian Oil sardine along Kerala coast. In: Jithendran, K.P.; Saraswathy, R.; Balasubramanian, C.P.; Kumaraguru Vasagam, K.P.; Jayasankar, V.; Raghavan, R.; Alavandi, S.Indian oil sardine (IOS), the commercially and ecologically important pelagic fish of the Kerala coast is susceptible to climatic variation. The study analyzes the impact of climate change on the catch of Sardinella longiceps along the Kerala coast and tries to predict the catch trend under the two RCP scenarios 4.5 and 6.0 for the period 2020-2100. Monthly catch of IOS by major gears for the period 1990-2016 was collected and Relative effort (Effort) and Weighted CPUE (cpue) were accordingly estimated. The climatic variables Sea Surface Temperature (SST), Precipitation (Pr), Chlorophyll a (SSC) and Salinity (SSS) were obtained from NOAA/NASA. The relationship of cpue and Effort of IOS to environmental variables were explored by Generalized Additive Model. The best fit model was selected using lowest Akaike information criterion (AIC) value, Deviance and F statistic. Predictions of cpue and Effort under RCP 4.5 and RCP 6.0 were done and the catch of IOS was estimated. The GAM model revealed the variations in the catch of IOS in relation to climate change. The SST, SSS and Pr showed a negative relation whereas SSC was found to be positively related to the catch of IOS. The results of the study indicate a decreasing trend of cpue and catch and an increasing trend of Effort towards 2100 under both climate change scenarios.

“…Among the diatoms, Fragilaria oceanica has been indicated as the favourite food item since sardine abundance has been correlated with its presence in coastal waters. Sardines from Omani waters also feed on phytoplankton (Piontkovski et al., ). The differences in proximate composition values among the variants may be due to their dietary habits, which need further investigation using a seasonal study design.…”

Morphological divergence in Indian oil sardine, Sardinella longiceps Valenciennes, 1847- Does it imply adaptive variation?

SummaryThe Indian oil sardine, Sardinella longiceps, is an important pelagic species in Indian waters, and shows divergent morphology while in sympatry. The reasons behind this divergent morphology were investigated using morphometric, genetic and nutritional analyses. Twenty-one morphometric characters (as percentage of standard length) and eight meristic characters were studied in the three variants to assess whether they are significantly diverged. Distinct clustering of morphotypes was evident in the principal component analysis on log-transformed ratios of morphological characters with PC1 and PC2, explaining 50.7% and 17
